.pplieation filed June 8, 1911. Serial No. 831,881.

T 0 all whom it may concern:

Be it known' that I, \VALnuMan Jens PETER OLSEN, a subject of the Kingof Denmark, having made his first declaration of becoming a citizen ofthe UnitedStates, residin at Brooklyn, in the county of Kings and tateof New York, have invented new and useful Improvements in Machines'forCapping Receptacles, of which the following is a full, clear, and exactdescription.

My invention relates to machines for closing the mouths of bottles withmetal caps or covers, and more particularly to the mechanism thereof forregulating the pressure of the capping devices.

The principal object of my invention is to provide such a machine withautomatic devices, which, when the requisite pressure is exerted uponthe cap to seal the bottle,

will release the actuating mechanism of the capping plunger and permitthe return of the same to its original position.

Another object of my invention is to enable the operator to regulate thesealing pressure at which the release of the actuating. mechanism of thecapping plunger will Still another. object is to permit of theadjustment of the position of the capping plunger and its actuatingmechanism ,to enable the machine to accommodate and cap bottles ofdifferent heights.

These and other objects I accomplish by the-means and in the mannerhereinafterfull. set forth, and'as more pointed out in the claims.

In; the drawin s: Figure 1 is a vertical. front elevation of my improvedcapping machine, having-the cap-magazine and hopper removed forclearness. F ig. 2 is a vertical'side elevation 'of the same. showingthe magazine and hopper in position. Fig. 3' is a top plan view of mymachine having the magazine and hopper removed as in Fig. 1. Fig. 4-is.a horizontal transverse section taken on the line H, Fig. 1. Figs.5,6.- 7 and 8 are diagrammatical fragmentary views of the plungerandactuating devices therefor. drawn to a arger scale. F ig. 9 is arearelevation of said actuating devices showing the-arrangement 0f thesame in pairs.- Fig. 10 is a top"plan.view of the samehav ng pne set ofactaatmg devices reparticularly moved. Fig. 11 transverse verticalsection taken on line 1l1l, Fig. 9.

Referring to the drawings, it will be seen form and have shelf-3 mountedupon their upper ends. These standards are preferably three in number,two being disposed in front of the machine and one in the rear. A suit-.

able revoliible turntable 4 is mounted near the rear of the machine,adjacent to one side thereof, in a horizontal plane slightly above thatof the platform Land the lower end of its vertically disposed shaft orspindle 5 is suitably journaled in the framework of the machine anddriven by means of a beveled gearing above shelf 3. A similar turntable6, of less diameter, is located on the opposite side of the rear portionof the machine and mounted on the lower end of the vertically disposedspindle 7.

Turntable at and turntable (3 are situated near the rear of the machine,one on each side of. the center of width of the same, and the verticalshafts 5 and 7 on which they are mounted are suitably journaled in the'framework of the machine, and are driven atthe same speed by atransverse horizontal shaft 22 through the medium of beveled gears onthe ends thereof..

A suitable runway 15 for feeding bottles to these turntables is,preferably, arranged with its side wallsin parallelplanes tangen tial toshaft 5, and the end portions of its sidewalls extend over turntable 4and are' flared to give proper direction to the bottles.

The edges of these turntables contact, and

immediately in front of this contact a vibratory switch-arm 16 ispivoted that extends toward-the mouth of runway 15 and vibrates from onede. wall thereof to'thc. other, to sweep every alternate bottle etl' orturntable 4 onto turntable 6. and directthe bottles not so moved ontoturntable -6 to,

what is known as the turret 8. Turntable 3.

tween which a series of pockets is formed 7 and i uto which the bottlesfrom the turntables are successively moved. In .order, however, toinsure their. moving into these pockets, the bottles of first oneturntable and then the other are engaged by the transverse blade 17, onthe lower ends of vertically disposed walking bcamslS. These beams, 18,are fulcrumed at their upper ends'on a shaft 18 mounted in the frameworkof the machine and their up er ends are provided with embossments t atengage cams .79 on the main-shaft 34 of the machine. They are kept incontact with said cams through the medium of coil springs 18*, and assaid cams 79 are arranged upon said shaft in positions just the oppositeof each other, the lower end of one of said beams'moves towardthe'turret in front of it to insure the bottles fitting into theadjacent pockets thereof, while the other moves away from its turret,vice versa. As the'turret-s revolve the bottles are he is in saidpockets for one-half a revolution y segmental guards 11, and until theforward edges of said bottles come in contact with the transverse wallsof gages 14-, which latter. are adjustable longitudinally, toward andfrom-the turret by means of set screws passed through slots in theextensions of the same into table 13 in front of the machine,in front ofwhich latter the operator stands to remove the bottles as they arecapped. This table has a central rearward extension which; has its uppersurface in the same lane as said table. Midway between the f i-ontportions of the turrets this extension is provided with guide-wall 12,the center of the transverse length of which is formed into a forwardlyprojecting point from which it curves backward and transversely towardthe turrets.

Just below their upper bearings the turret shafts 10 are provided withcircular disks 19, and these disks have a series of equidistant studs 20projecting from their upper surfaces. I prefer to have but four of thesestuds 20 so that when engaged they will move the disks and turret-shaftsonequarter of a revolution and bring two of the pockets of the turret(with the bottles I therein) to the front immediately back of the gages14 in position to be simultaneously capped or closed, by the mechanismhereinafter to be fully described. These disks are actuated by pawls 27,the engaging ends of which are formed to correspond somewhat to theshape of the thumb and index finger of the human hand. The portioncorresponding to the finger curves toward the rear, and the partcorresponding to the thumb is engaged by the studs 20. The pawls 27extend toward the central portion of the machine and are pivotedrto theunderside of a transversely reciprocal bar 22, which latter has hearingsin the framework of the machine that guide its movements.

of the f These pawls have'lugs 25 exte nding rearwardly' from the bossesends, and a coil spring 26 is interposed between these ends, thefunction of which is to keep said pawls constantly in engagement withthe studs 20 of disks 19.

' The bar 22 is reciprocated by a horizontal vibratory arm 24 theforward end of which is suitably pivoted to the underside-of the sameetween the pivots of pawls 27. Arm 24 is disposed in a horizontaldirection and its rear end is rigidly secured to the lower end of ashaft 28. Shaft 28 extends up through a hollow standard 30 and its upperend has the boss of a transversely extending, comparatively-long arm 29suitably secured thereto. The movable end of this arm terminates at apointslightly beyond the plane of the side of the machine and has aballjoint connection with the rear'end of a link 31, the forward end ofwhich latter is pivotally connected to'a head journaled on a projectingcrank-pin 32 of a wheel 33 on the adjacent end of the main-shaft 34. I

The cap-blanks are preferably stored in a magazine 35 mounted in asuitable bracket. projecting forward from the upper portion rameworkconsisting of sleeves 58, adjust-ably mounted on the upper ends of thefront standards 2, 2, and connected by cross-bars, 58, as will behereinafter more fully described. From this magazine cap.- blanksgravitate into a substantially funnelshaped hopper 36, and

the discharge opening in the lowermost portion of the same, which is soconstructed and arranged that the blanks are fed from the lowerrearwardly curved discharge mouth 38 in substantially a horizontal planeto their proper position in the lower end or head 89 of acapping-plunger 40 ready to be clamped down upon the mouth of thebottle; In the machine here illustrated I have shown two pairs of thesecapping plungers, but I desire'to state that any number may be employedthe machine. They are all identical in construction and are operatedeach in the same manner, the operative parts being merely duplicates.Therefore for the convenience the constru of but one plunger will withthe understanding apply to all.

The plunger 40 comprises a vertically reciprocal bar, substantiallrectan ular in cross-section, the upper end of whic is slidably mountedin a bearing 41 in a rearwardly projecting memher of the cross-barsconnecting the bosses of the U-shaped bracket 58*, which latter aresuitably secured to the upper ends of the front standards 2, 2. This'baris bored out its entire length to form a hollouuchamber 44, and its tionand operation purposes of of their pivoted this hopper has a chute 37removably secured to the walls of according to the necessities of bedescribed herein,

:.with a central opening 46 of approximately the same diameter as theoutside dimension of the cap of the bottle after it is clamped on thebottle. A. transverse (horizontal) slots? is cut in this-head whichregistersazwith the mouth 38 of the feed-chute 37 hereinheforementioned,below which the opening 46 is widened to form a flaring sleeve 48 thatguides and centers the head of the bottle to make itregisteig' with saidcap.

A hollow sleeve 49 of suitable thickness is fitted in the'upper portionof the bore-44 of the==pluriger bar that extends down about one-half thelength of said plunger where it abuts against a bushing 50. This bushing2o l'iaS a restricted bore and, together with the 3 bore of the lowerbushing and the reduced borein the upper part of the plunger, acts as aguide for a suitable rod 51, which latter hastits lower endscrew-threaded and has 5 0.. flanged head 'or ejector-plug 52' securedthereto. A shoulder 53, made byreducing the. diameter of the lowerportion of said rod, limits the downward movement thereof and a coiledexpans1on-sprmg 54 surrounding the said rod between the bushing and theejector-head 52 on its lower end keeps said rod normally in the positionshown in Fig. 5.

The throw or vertical reciprocal move- ;.ment of the plunger is limitedby a forwardly projecting lug that'is secured'to its upper end, and isadapted to. engage the upper-and lower parallel ,stop-lugsoti and 5f?projecting rearwardly from upper and lower cross-bars 58, which latterconnect sleeves 58 mounted on the upper ends of the standards 2 at thefront corners of the machine. These cross-bars and' sleeves constitute aframe which vertically adjustable by means'of an internallyscrewthreaded column (10 depending from the center of length of thelower cross-bar, andengaged by a centrally located screw-shaft. (51,which latter is rotated through the mo- -dium of a worm-gear (32mounted.thereon, and a worm on a horizontal shall ()3. This horizontalshaft is arranged transversely and its opposite end is provided with ahand-whecl t'i-l, by manipulating which the ,1ramework carrying thestop-lugs 5G and 57 and the magazine or hopper for the capblanks, israised or loworcd so as to adjust the bottle-capping mechanism to thediff0]'t 11t heights of bottles.

Secured to the plunger 40in any suitable manner (preferably removably bymeans of a frictional clamp (35), is a longitudinally dispcsvdrraruardly facing vertical. rack (36, which is engaged andrcci-procate'd by 5a suitable segmentalgearj 67, The boss of willcontinue to move this gear 67 is loosely mounted on a transversedrive-shaft. 68, and it forms an important part 'of the mechanicalmovement that accomplishes the sealing of the bottle by loweringt-he'plunger 40 against the cap.- The portion of the boss of the gear onthe side opposite its gear-teeth is provided with a suitably shapedenlargement 69, extending, preterably, in a plane parallel to the planeof said gear, and is bored out to form a tangential pocket 70, in whicha coiled expansion spring-71 of relatively high tension is seated. Ashoe72 is placed in the outer end of this pocket and is pressed against thespring71 by means of a setscrew 73 tapped through the lateral member'ofan inverted Lshaped arm 74= .pivotally secured to the side of asuitable link 75. This link 75 is pivot-all mountedon the outer extendedend of a olt 76tapped into a lateral lugo-n'said enlar ement 69, andopposit'e its .pivot itis, pre erably, bifurcated and has a roller 77mounted between the arms thereof. When the spring 71 has been compressedthe tendency of link 75 is torise, but this is prevented by a'cam 78rigidly mounted on and rotatable with drive-shaft (5 8, above mentioned.

Assuming the capping plunger ca1n 78, and the connected elements onshaft 68, to be in normal position, (shown in Fi s. 5, 9, 10 and 11), asshaft 68 rotates in t c direction of the arrow the cam 78 movestherewith until the oflset portion thereof comes in contact with roller77 on the endlink 't' 5. spring 71, the link will not now be rotated onits-pivotbut will move around with cam 78 carrying the segmental I ear67 and its connected parts along wit it; and thus to, the V move plunger40 downwardly until its-head comes in contact-with the head of thebottle to be capped. Experiment has demonstrated the fact that apressure of approximately seven hundred pounds (-700 lbs.) is the mosteilicicnt tense in capping and sealing a bottle containing liquids. Forthis reason the spring'l'l is compressed until a similar pressure isobtained thereon. Now,

during the transmission of the movement of the drive-shaft 68 to cam 78,'the plunger ownward until the resistance resulting from the cappingoperation. overcomes the resistance 0 spring 54:, which will be greaterthan seven hundred pounds (700 lbs.) whereupon" cam 78 will push link 75outward and release segmental gear GT and its conjunctive parts and the.spring '54 will be freeto expand. For example: after the plunger hasreached the bottle,and the cap brought into-contact with cap onto thebottle and any'further move- 7 the same, said plunger continues itsdownment of the plunger would robably break the bottle. At this momentte embossment onthe periphery of cam 78 will move past the roller, asillustrated in Fig. 7, and the Segmental gear 67 and its connected partswill remain stationary in the position they assumed as the cam wasreleased.

In order to return the plunger to normal position again it is necessaicyto move the segmental gearin a reversedirection to the rotation of shaft68. This is accomplished by means of a cain 79 keyed to the main 'shaft34 which is parallel to'and rotates at the same speed as shaft 68 but inreverse direction thereto. This cam 79 has one face 81 that is arrangedsubstantially radial from its axis that is adapted, a moment after therelease of the pressure on the bottle, to engage a roller 82 mounted onthe adjacent side of the oppositely extending enlargement 69 of the semental gear 67. As cam 79 moves forward the parts connected to the seental air and the enlargement, (inclu ing the link-75 and L-shaped arm74 carried thereby) will move in a reverse direction on shaft 68 untilthe plunger has been raised the full limit of its upwardmovement'oruntil the roller 82 has passed out of engagement with the cam79.

When the machine is in operation, in

a order to prevent a bottle becoming wedged in the throat 46 of theplunger, and be in danger of being raised by the same, I have provided asimple device for this purpose,

' This consists of a transversely disposed slide-plate 83 reciprocablymounted in a horizontallydisposed guide-bloc k84 secured to the upperend of the plunger 40; This is kept normally at one end of its movementby a coil-contraction spring 85 and has a suitable shoulder 86 on itsupper surface. A roller 87 is journaled on a horizontally disposed pinprojecting from a sleeve 88 adustably mounted on the upper extended endof the rod 51. The outer end of slide-bar 83 has a roller 89 journaledtherein, and this roller is adapted to engage the inclined surface of aninverted acute angle L-shaped bracket 90 bolted to the under surface ofthe upper stop-plate 56. Innormal position (Fig. the rod 51 is elevatedon the shoulder 86 of slide. 83 by reason of the engagement of therollcr 89 with the inclined face of bracket 90 which has pushed slide 83to the right. Owing to greater tension of spring 54 on rod 51- the slidewill not be drawn back by spring 85 until said rod 51 has been slightlyraised by the operation of capping a bottle. and when plunger -10 israised the rod will remain in contact with the capped bottle until thelatter has been forced out of the throat of the plunger. During thereturn of the plunger. \vhcn the bottle is wedged, the head 52 on therod 51 will engage and eject the bottle. from the tapered throat owin tothe pressure of the spring 54 surrounc ing the piston. The

arts will then be in the position shown in ig. 8; the roller 87 restingupon the lowest surface of the slide 83, and upon the raising of theplun er.40 the bottle will remain upon the tab e or bed of the machine,while the roller 85 will engage bracket 90 and force said slice-bar 83longitudinally so that the rod 51 will bedrawn upwardly in the plunger.Thiswill elevate the rod 51 so that its lower end is high enough topermit the next cap to be fed into the lower end or head of saidplunger,this movement of the rod being caused by the shoulder 86 of theslide bar engaging and elevating the roller 7 on the upper endof the rod(see n operation, the bottles are fed from the runway 15 onto therotatable table where they are separated by switch-arm 16 so thatapproximatelv every other air of bottles will pass to the rotatable tabe 6. Stops 11 halt the further movement of the bottles and therespective walking beams 18 operating in conjunction thcrewith'will movealternately inwardly and shift each pair of bottles into two of thepockets of their respective turrets 8 wherein said bottles continue totravel intermittently in a rotary path until they arrive under the ropercapping plungers. Said plungers ave a. reciprocatory movement in avertical plane that is impartcd to them through the medium of thesegmental gear 67 and rack 66 driven by shaft 68. The plunger having Ireceived a cap-blank from feed-chute 3T38 is moved downwardly by theengagement of cam 7 8 with arm 75 until the compression on the spring 71has reached a point suiticieut to firmly crimp the cap on the bottle andseal the same. At this point the pressure of the spring is overcome bythe cam passing the arm 75 while the can; 81 engages roller 82 on theopposite edgmof segmental gear 67 and moves the latter in the oppositedirection, 5. 0., upwardly to raise the capping plunger and restore thesame to its normal position. During this capping period, the ejectingrod 51 has been more upwardly through the plunger by the bottle so as topermit the cap and neck thereof to enter the contracted throat 46 andupon the return movement of said plunger said rod has been kept pressedout through the bottom of the plunger by the spring 54 until the bottlehas been ejected from the plunger head. Before the plunger reaches thelimit of its upward movement, the mechanism at the top thereof will beactuated and the rod 51 restored to its normal'position and the dcvicc ithen ready for the next capping opcrallou.
